Graphing transformations: y=3 f(-x) (picture below, all the way at the bottom)

I know that I'm suppose to flip it over the y-axis, but I don't understand the stretching part.
@Easyaspi314
Are you told that f(x) = f(-x) in this problem? What else are you told besides the graph you posted?
stretch by 3(simply multiply each point you graphed by 3, that will stretch your graph
That's all I'm told, oh and this 0<=x<=4
You flip over the y-axis only if you were told that either f(x) = f(-x), or that f is an even function, or it is symmetric about the y-axis.
You need more info, because you dont know if f(x) = f(-x).
That is, in the graph you provided, f(2) = 1. We know nothing about f(-2).
Unless something in the directions alludes to f(-x).
We could graph 3f(x). Thats not a problem.
